tetraethyl 2,2'-(1,4-phenylenedimethylidyne)bismalonate Chemical Properties,Usage,Production
Uses
UV-988 is a high-absorption UV absorber developed specifically for transparent polymer materials. It effectively absorbs the UVB band of ultraviolet light, which is sensitive to PC/PET/PMMA materials, reducing UV damage to the substrate. This allows the material to withstand various weather conditions and maintain good optical and physical properties even after long-term use. Consequently, it extends the lifespan of solar panels and films, achieving the goal of aging resistance.
